Vasco da Gama in context: Street-network sprawl trends

The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Vasco da Gama plotted against Goa and India. While Goa and India both followed a zig-zag trend with an overall increase, Vasco da Gama's new street additions followed a zig-zag trend with an overall increase. Most recently, Vasco da Gama's incremental SNDi rose from 5.53 to 6.29 between 1991-2005 and 2006-2020. In terms of the aggregate network, Vasco da Gama ranked 5th out of 5 cities in Goa and 1575th out of 1868 in India as of 2020.

Rankings go from most connected to most disconnected — rank 1 is the most connected.

What about similarly populated cities?

• Rimini, Italy
• Klaipėda, Lithuania
• Darmstadt, Germany
• Puno, Peru
• Würzburg, Germany
• Yangling, China

In new street additions, Vasco da Gama fluctuated in its street-construction patterns, while Rimini built increasingly disconnected streets from 1975 through 1991-2005, then improved and Puno built increasingly disconnected streets over time. For the full street network, though, all three cities follow the same trend. Vasco da Gama and Rimini have been growing further apart in their street-network character since 1975.
